(57) The present disclosure relates to a battery module using insulating oil, and a battery
pack including the same include a battery cell stack, in which battery cells each
formed of edge surfaces and flat surfaces are stacked, electrode leads formed so as
to protrude from the battery cells, a frame formed of the upper, lower, left, and
right surfaces and covering the upper, lower, left, and right surfaces of the battery
cell stack, and end plates covering front and rear surfaces of the battery cell stack,
wherein space parts are formed between the edge surfaces and the frame and between
the edge surfaces and the end plates, and insulating oil for cooling the plurality
of battery cells is filled and flows in the space parts, and the insulating oil makes
contact with the battery cells and the electrode leads.
